Imploring Hearts (al-Qulub- al Daria)is a collection of prayers selected and compiled into a single volume by M. Fethullah Gulen from various sources, particularly from a three volume work entitled the Compendium of Litanies (Majmu'at al Ahzab), a compilation of prayers by the late Ottoman scholar Sheikh Ziyaeddin Gumushanevi (1813-1893). Only the introduction to the book is English; all prayers are provided in Arabic with no translation.
